Noma yiluphi ushintsho olungathinta ukucushwa kwe-beacon evunyiwe kufanele lulandele indlela yekhasimende yokulawula ushintsho.
Okufanele Uthumele I-Highleap Ukuze Ubuyekezwe Ukukhiqiza kwe-PLB
Ukuze uthole isibuyekezo sokukhiqiza se-PLB, nikeza iphakheji yokuklama ye-PCB evunyiwe, imininingwane yokukhiqiza, ulwazi lwe-BOM, i-RF kanye ne-antenna, imininingwane yebhethri, imidwebo yomshini/yokuvala, amafayela okuhlanganisa, imiyalelo ye-firmware kanye neyohlelo lobunikazi, izidingo zokulandelela, indlela yokuhlola ukukhiqiza ephephile kanye nobuningi obudingekayo ukuze kube nohlobo lweprototype, ukwesekwa kweziqu, i-pilot noma ukukhiqiza.
I-Highleap ingakhiqiza futhi ihlanganise ihadiwe ngaphakathi kwalowo mngcele okhululiwe. Noma yiluphi ushintsho ezingxenyeni ze-RF, ukuphathwa kobunikazi, uhlelo lwebhethri, inethiwekhi ye-antenna noma ezinye izinto zokucushwa ezivunyiwe kufanele zibuye ngenqubo yokulawula ushintsho lwekhasimende kunokuphathwa njengokushintsha kokuthenga okuvamile.
Umphumela ofanele akuyona ifektri "evivinya kakhulu" ngokudlulisa isexwayiso sangempela sokucindezeleka. Kuyinqubo elawulwayo esebenzisa ukuzihlola okuvunyelwe, i-simulator, ukusetha okuncishisiwe noma enye indlela echazwe ngamakhasimende efanele uhlelo, ngenkathi kulondolozwa ukulandeleka kusukela esihlokweni sokuqala kuya kumayunithi okukhiqiza athunyelwe.

Ungasithola kanjani isilinganiso sama-PCB
Ake siqhube ukuhlaziywa kwe-DFM/DFA bese sibuyela kuwe nombiko. Ungalayisha amafayela akho ngokuphephile ngewebhusayithi yethu. Sidinga ulwazi olulandelayo ukuze sikunike isilinganiso:
-
- Gerber, ODB++, noma .pcb, spec.
- Uhlu lwe-BOM uma udinga ukuhlangana
- Ubuningi
- Isikhathi sokushintsha
Ngezinsizakalo ze-PCBA, sicela unikeze i-BOM yakho (I-Bill of Materials) kanye nanoma yimiphi imiyalelo ethile yomhlangano. Siphinde sinikeze ukuhlaziya kwe-DFM/DFA ukuze uthuthukise imiklamo yakho ukuze yenziwe futhi ihlanganiswe, ukuqinisekisa inqubo yokukhiqiza eshelelayo.
